    Default D4D Suspension Issue

    Some advise please gents...

    I've recently noticed my D4D leans to the left, see photos below, first pic shows the full weight and lean to the left, second photo vehicle is on a lift and the lean is less but still there...

    When measuring from the bottom of the rim to the bottom of the wheel arches there is a 30mm difference both front and back left.

    The vehicle is fitted with OME Constant 600, with heavier coils in the front to compenate for the winch.

    What would cause this to happen, and what is my solution? It's started to sag recently and not sure what the caused it.

    Thanks.

    Might be the case that only one of the leafs in the pack had broken. Might be possible to find a replacement for it

    How can the vehicle lean to a side when it is on a lift? (all 4 wheels off the ground and supported on the chassis rails?) Surely that points to another issue than the leafs?

    I have not gotten a quote to replace yet, two of the solutions was to have the leaf springs and coils reconditioned, or fit air suspension - I'm not so sure about either of these as a permanent solution... replacing the entire suspension is going to be very expensive!

    I have no idea, I have heard of a leaf spring collapsing or coil collapsing, but both on the same side of the vehicle at the same time is suspect...when on the lift the lean should not be there as the chassis should be carrying the weight not the suspension?

    Not to suspect the worst, but check your chassis to ground measurements on a few points as a precaution.

    It can also be that the supports on the lift are uneven and causes the lean in the air. If the supports are at equal height your vehicle should be perfectly level in the air.

    It might be the front coil pulling the nose down and raise the Right rear as well - easy to check is to swap front shocks with coils from left to right, wont be to expensive to do this exercise, then you will know where is the problem
    Easier to swap the front shocks with coils than the rear leaf springs
    I would start there to be sure where the problem is.

    Just a question. Found this on a Isuzu once, but not sure of Hilux construction. Could it not be due to collapsed cab/bin mounting rubbers?

    Take the vehicle to Darryl at Mikem Suspensions in Selby
    He will do a free inspection and provide advice and a solution to your problem pronto.

    Just an update....

    So I finally got around to taking the vehicle to someone who knows more than me.

    The bushes on the front shock are shot, as well as those on the rear leaf spring. They reccommended replacing front shocks, bush kit on the rear (might as well do both sides), I'm also considering doing the back shocks while we're busy.

    Question is now to replace with Old Man Emu again, or change to Iron Man... Iron Man Foam cell is the cheaper option at the moment, I'm awaiting more quotes.

    Those bushes on front shocks must be tightened only after settling with weight or they can fail quite quickly.
    I normally leave slightly loose quick spin around block, come back and tighten properly while still on 4 wheels.

    yes - he was complaining about my amarok not siting level after he put some springs in.

    To be honest I could not see any issues, but he kept the wagon for another day or two, and was measuring the chassis and springs and all sorts of things, only to determine that it was my load bin rubbers that had collapsed as suggested above.

    Either way he would get to the root cause of the issue and I believe his solutions are every bit as good as the imported stuff.

    I have mentioned before, the engineers handbook to suspension design, sitting on the office desk, would indicate that he has matric and probably knows more that most of the armchair experts.
